Specification of Letters Patent.

Patented Aug. 3, 1915.

Application filed September 16, 1914. Serial No. 861,987.

T 0 all whom it may concern:

Be it known that I, RAYMOND C. DOLE, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Staniping-ltlachine; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference -marked thereon, which form a part of this specification.

This invention relates to the stamping of sheet material, but is not restricted to such use as it may be used in any connection for which it may be adapted or appropriate.

The object of my invention is the pro vision of an improved apparatus of the character described, which is simple and eflicient in its operation, inexpensive in its construction, and which has a dual action, in that a single movement of the coacting parts thereof accomplishes both a stamping and a feeding of the material acted on.

Further objects and advantages of the invention will be apparent from the following detailed description thereof.

The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,

Figure 1 is a side elevation of an apparatus embodying the invention. Fig. 2 is a sectional view thereof taken on the line w, 05 in Fig. 3, with parts broken away. Fig. 3 is a vertical section on the line y, 2 in Fig. 4, and Fig. 4. is a front elevation of the apparatus.

Referring to the drawings, 1, 1 designate the opposing side standards or frame parts of the machine, which standards are connected at their lower ends by a shaft 2 and at their upper ends by a shaft 3. The shaft 3 is mounted for rotation in suitable bearings in the upper ends of the standards, and, in the present instance, carries a belt pulley 4 at one end and a fly-wheel 5 at the other end thereof without the respective standards.

Mounted on the shaft 2 between the standards 1, 1 for rocking movements relative thereto is a rocker-frame 6, in the'present instance, of inverted U-form with the lower or free ends of the legs thereof provided with bearings for loosely receiving the shaft 2, and with the upper or looped portion thereof forming a table for opposing the thrust of the stamping units hereinafter described. A stamping-head 7, in the present instance, of Uform, is suspended from offset or eccentric crank portions 8 of the shaft 3 above the table portion of the rocker-frame 6 and has an arm or guide-bar 9 projecting downward from each end thereof and into a registering guide-way 10 provided vertically in the respective end of the rocker-frame 6. This connection between the rocker-frame 6 and stamping-head 7 maintains them in constant longitudinal allnement, so that a unitary rocking movement will be imparted thereto with the shaft 2 asan axis when the shaft 3 is rotated. The shdlng engagement of the arms 9 and rocker frame 6 will, however, permit the stampinghead 7 to have to and fro movements relative to the rocker-frame 6 when the shaft 3 is rotated, due to the changing of the hori- Zontal position of the eccentric crank portions 8.

The stamping-head 7 carries one or more stamping units 11, in the present instance five in number, which units, upon a converging movement of the head 7 and rockerframe 6, cooperate with the table portion of said rocker-frame to stamp a strip of sheet material 12 fed therebetween. The stamping units 11 may either be in the form of dies for cutting articles of desired shape from the strip 12 or they. may constitute printing units for stamping any desired information or designating marks on the strip 12. To illustrate, the present machine is designed for the printing and stamping out of pasteboard milk bottle stoppers or disks, and in such case the units 11 are first adapted to stamp the desired printed matter for the stoppers on the sheet 12, and are then changed to cut the printed disk portions from the sheet upon a subsequent feeding of the same through the machine.

It will be noted that the stamping units 11 are carried in a removable manner by the head 7 to facilitate an easy changing and substituting of the same. In the present instance, the units 11 have shanks which project upward through registering openings in the head. 7, and are secured to the head by nuts 13 threaded to the upper ends of the shanks.

The rocker-frame 6 is preferably provided over the top or table portion thereof with a stripper plate 1 1, which is vertically spaced therefrom to permit the passage of the material strip 12 between the plate and table, and has openings 15 in register with the units 11 for such units to pass through in the stamping operation.

The material strip 12 is supported at opposite sides of the rocker-frame 6 by table portions 16, 16, which connect and are supported by the standards 1, 1. At one side of the sheet stamping means is disposed a pair of feed-rolls 17 between which the sheet 12 passes, one of said rolls 17 being yieldingly urged toward the other by springs 18, and the other having its shaft provided at one end with a sprocket-wheel 19, which is connected by a sprocket-chain 20 to a sprocket-wheel 21 on the crank shaft 3. The stamping parts also have a feeding action on the sheet 12, the rotation of the crank 3 being in the direction indicated by the arrow in Fig. 3 so that the stamping head 7 will swing downwardly during a rocking of the stamping members 9 and 7 toward the feed rolls, thereby placing the stamping parts in coaction with the sheet during the forward rocking movement of the rocker members. It is therefore apparent that the feeding action of the feed-rolls 17 must be timed to work in unison with and to move the sheet 12 at the same speed as it is moved by the action of the stamping parts when in engagement therewith.

It is evident from the above description that a rotation of the crank-shaft 3 will cause a rocking of the stamping means with the shaft 2 as its rocking axis, and will also cause a relative to and fro movement of the stamping parts which are disposed at opposide sides of the stock sheet being acted on, whereby said parts are moved into stamping coaction with the sheet at one portion of a rocking stroke of the stamping means and will recede from each other at another portion of such stroke.

I wish it understood that my invention is not limited to any specific construction, arrangement or form of the parts as it is capable of numerous modifications without departing from the spirit of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is,-

1. In a machine of the class described, rocker means having relatively movable cooperating stamping parts mounted for coaxial rocking movements, and means operable to simultaneously rock said rocker means and to impart relative movements to the parts thereof.

2. In a machine of the class described, rocker means having cooperatlng stamping parts relatively movable in a radial plane relative to the rocking axis of said means, and means operable to simultaneously rock said rocker means and impart relative stamping movements to the stamping parts.

3. In a machine of the class described, a single rocker means comprising a table part and a stamping-head, the stamping-head being movable toward and away from the table in a plane intersecting the rocking axis of said means, and means coacting with the head to impart movements thereto relative to the table and also to impart rocking movements to the rocker means.

4. 111' a machine of. the class described, a single rocker means having relatively movable coiiperating stamping parts, and a crank shaft operable to simultaneously rock said means and impart relative movements to the stamping parts thereof.

5. In a machine of the class described, a rocker frame having a fixed rocking axis, a stampinghead connected to said frame for rocking movements therewith and for to and fro movements relative thereto in a plane which is radial to said rocking axis, and means for imparting to and fro movements to said head and rocking movements in unison therewith to the head and rocker frame.

6. In a machine of the class described, a stationary frame, means carried for rocking movements by said frame and having stamping parts relatively movable in a plane which is radial. to the rocking axis of said means, a crank shaft operable to impart rocking movements to said means and rela tive stamping movements to the parts thereof, and means for feeding sheet material between the stamping parts of said rocker means.

7. In a machine of the'class described, a rocker frame having a fixed rocking axis, a stamping-head having parts in radial sliding engagement with said frame whereby the rocking movement of the frame is controlled from said head, and a shaft having eccentric portions carrying said head whereby a rotation of the shaft will reciprocate said head relative to the rocker frame and impart unitary rocking movements to said head and frame.

In testimony whereof I have hereunto signed my name to this specification in the presence of two subscribing witnesses.
